Pain monitor aims to cut opioid use during surgery
NCT ID NCT04402242
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a device called the NOL monitor, which measures pain levels during anesthesia. The goal was to see if using this monitor could help doctors give less remifentanil (a strong painkiller) during major abdominal surgery. The study planned to include 90 adults, but it was stopped early, so the results are not complete.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could show that NOL monitoring helps tailor pain medication during surgery, potentially reducing side effects.
What could go wrong
The study was terminated early, so we don't have enough data to know if it works. It was also a small, single-center trial.
